Queens-logo The scope of work for this research project at the Robert M. Buchan Department of Mining Engineering dealt with the "Evaluation of the potential for piping of tailings through a hole into a geomembrane and into the underlying foundation". The research took place over three years and involved the study of liner design for tailings impoundments. The Principal Investigators are Dr. Kerry Rowe and Dr. Richard Brachman. KCB is providing ongoing funding to Queen's University on other research on tailings liner systems, including cold weather applications and aging tests considering tailings geochemistry.
